Once she'd finished filming Harry Potter, Emma Watson shocked the world by chopping off all of her hair. Emma sported this cute elfin crop at the Harry Potter and the Deathly Hallows: Part 1 World Film Premiere in London.

The Twilight star has done many things to her barnet over the years. Whether that's for her role as Joan Jett in The Runaways, where she went short and punky or orange for, well, we're not sure. Basically, she's happy to experiment, which is why we love this adrogynous hairstyle on her.

The Amazing Spider-Man star has gone for an array of colours over the years - from red to brunette, to blonde, to red again and then back to blonde. While we love Emma with any kind of shade, we have to admit that this one is our favourite look.
